Abstract:
Device for storing two products separately and dispensing them simultaneously comprises a necked container, a covered flanged cup sealed in the neck with its flange lying on the rim of the neck, a trocar above the cup in alignment therewith, removable tear-strip for holding the trocar away from the cup, and means for guiding the trocar to pierce the cup when the tear-strip is removed.
Abstract:
A coupler-aspirator-valve assembly includes a coupler-aspirator having two flow passages joining in a nozzle. Each flow passage communicates with a chamber. One of the chambers houses a valve stem which couples to a valveless propellant cartridge. The other of the chambers houses a product container valve stem which couples to a valveless product container assembly.
Abstract:
An initially sealed closure having a top, sealing means for forming a seal against a container neck and means for engaging such a neck so as to hold the sealing means in a sealed relationship with the neck can be formed with an initially sealed dispensing opening, an integral strap capable of being partially severed from the closure and a subclosure carried by the strap. With this structure the strap can be partially broken away from the remainder of the closure so that the subclosure can be used to close the opening.
Abstract:
Container-piercing apparatus, wherein an inwardly tapered cup member is provided with an opening into the innermost region thereof for admitting a piercing member. The cup and the piercing member are supported for movement of one relative to the other so that the last-mentioned member can be admitted through the inner opening of the cup in a direction enabling engagement of the piercing member tip with a container received in the cup. Support of the piercing member and the cup for movement along a path transverse to the foregoing direction is provided so that the piercing member tip can be centered with respect to a predetermined location on the container as the container is received in the cup. For conveying fluid from or to a pierced container, the piercing member includes a chamber and a pair of spaced openings which communicate with such chamber.
Abstract:
A tear gas gun is mechanically maintained in a normally cocked position by an electrical resistor connected at one end to a firing pin while the opposite end of the resistor is secured to a stationary surface. The firing pin has a projection extending therefrom which is normally engaged by an electromagnetic latch. The latch is mounted on the plunger of a solenoid energized to cause displacement of the latch to a release position. An electrical control unit has a firing switch connected to the resistor for causing burn-out and disintegration of the resistor upon energization of the solenoid thereby permitting firing action by the firing pin.
Abstract:
A diaphragm valve for sealing a chamber which consists of a rupture disc, a hollow knife, a power spring, a power spring retainer and a bellows motor. The hollow knife is positioned by the power spring retainer adjacent to the rupture disc. A bellows motor, suitably positioned at the head end of the knife, provides the force, when initiated, to force the knife into the disc to rupture it thus permitting air to fill the chamber through the hollow knife body. The device may also be activated manually with the power spring providing the driving force to the knife.
Abstract:
A dispensing unit for simultaneously puncturing a plurality of sealed pressurized containers so that each container has open communication with a common dispensing tube that in turn has a closed valve end which, when threadably connected to a hose, will dispense all of the pressurized contents of the containers.
Abstract:
Apparatus for dispensing effervescent liquid contents from a container and for sealing the container when a portion of the contents remains therein. The apparatus includes a first valve structure carried by the container and a second valve structure selectively attachable to the first structure in a manner that operation of the second valve structure will operate the first valve structure to permit the contents of the container to be dispensed.
Abstract:
A fast charging medical oxygen dispenser including a specially designed valve which has a fixed valve seat and a freely movable valve body. In dispensing position the valve body nests closely within the valve seat with the valve body having an extremely small dispensing opening which allows the gas to pass from a storage space and then through the valve for dispensing purposes. In fast charging condition the valve body is urged somewhat away from the valve seat with the valve body having an enlarged slot which is closed off during the dispensing action, but which is opened when the valve body is urged away from the valve seat so that gas can quickly pass through the enlarged slot and into the storage area.
